Option to have summaries (totals)VAT excluded

I do not need to care about VAT, however at summary/dashboard level, I mostly don’t care about VAT (collected or paid) : this amount belong to the state.
I still do care a little (to monitor cash flow level)
Suggestion :
Add an option to display either “with VAT” (current display)," “mixed” (VAT + excl. VAT) or “only exc. VAT” in summaries/dashboard

Here is a mockup illustrating the “mixed” mode (UX/UI to be revised :-) ) :
